ANBU

6 ANT

Events

Itachi becomes a double agent for Konoha to prevent the Uchiha revolution.

After 6 months of Itachi being an ANBU, Shisui is ordered to "keep an eye" on Itachi due to his change in behavior.

(About this year) Danzō orders Itachi to massacre the Uchiha clan. He seeks out Madara Uchiha for help and kills Shisui Uchiha to obtain the Mangekyō Sharingan.

Itachi joins the Akatsuki.

After losing his hand in a battle with Itachi[35][36], Orochimaru leaves Akatsuki[37][38].

The Fourth Kazekage starts ordering assassination attempts on Gaara, trying to kill him before he gets too dangerous[39]. The first attempt by his uncle Yashamaru drives Gaara insane, making him carve the kanji for love (愛, ai) into his forehead[40].

↑He died when Hinata Hyūga was three, in 3 ANT, at age 42. 3 ANT - 42 years = 39 BNT.

↑ 6.06.1They likely died during the Uchiha Massacre at age 46. The Massacre happened in 8 ANT. 8 ANT - 46 years = 38 BNT.

↑He likely died during the Uchiha Massacre at age 45. The Massacre happened in 8 ANT. 8 ANT - 45 years = 37 BNT.

↑He died during the Uchiha Massacre at age 40. The Massacre happened in 8 ANT. 8 ANT - 40 years = 32 BNT.

↑ 9.09.19.2Assuming Obito is the same age as Kakashi, then the battle that killed Kakkō, Taiseki, and Mahiru happened in 1 BNT. With the ages given in the second databook, their birth years can be calculated.

↑She died during the Uchiha Massacre at age 35. The Massacre happened in 8 ANT. 8 ANT - 35 years = 27 BNT.

↑He died when he was 27 (second databook) and when Gaara was 6 (See Yashamaru's death). Gaara was born in YNT, so he was 6 years old in 6 ANT. Yashamaru was born 27 years before that, in 21 BNT.

↑He likely died during the Uchiha Massacre at age 25. The Massacre happened in 8 ANT. 8 ANT - 25 years = 17 BNT.
